Hi everyone, I’m new to TeNPy and have a question about core usage for large bond dimension calculations. What is the optimal number of cores in such cases? Is it generally true that using more cores results in faster computations? From my experience with other DMRG codes, the optimal number of core...

to put this a bit into perspective, 30 minutes of runtime is often still considered very moderate, state-of-the-art DMRG calculations for publications in journals often run several days to weeks on high-performance-computing cluster nodes with >30 cores (more powerfull than a laptop...)
